feedback on ZCatalog section of Zope Book
by Josh Zeidner 13 Dec '00

13 Dec '00

I tried out the example in the Zope book and found that the ZCatalog aware example only works if you create the "default" catalog as explained elsewhere( must be named "Catalog" ). Am I doing something wrong or is this an error in the book? -keep up the good work! Josh Zeidner

XEmacs DTML Mode
by Alastair Burt 13 Dec '00

13 Dec '00

I have made many changes to my DTML Mode Howto and the associated files, which can be found here: http://www.zope.org/Members/alburt/dtml_mode.html The Howto explains how to get the benefits of Lennart Staflin's PSGML mode when editing DTML code. PSGML is a wonderful package for structure-based editing of SGML and XML code. There are menus and commands for inserting only contextually valid tags, it will identify structural errors and help indent the code appropriately, and attribute values can be edited via popup menus or in a separate window. The Howto explains how to get all of this for editing DTML. The technique is based on using a DTD for HTML with DTML tags added and with some Elisp code that extends the basic SGML/HTML mode. Since I first put this on zope.org, I have made the following changes: * Changed the DTDs so that they are now more consistent. * Changed the Elisp code to allow you to specify the enclosing element for a chunk of DTML+HTML code, so that the editor always knows what the valid tags are. * Added code to automatically add "-*-" mode declarations at the top of the file, so that on subsequent visits the file is always edited in dtml-mode. * Added commands to swap between HTTP and FTP access of the same objects. In particular, when you are editing a DTML file via FTP with three keystrokes you can pop to the management screen for the object in Emacs' W3 web browser. This functionality comes on top of the transparent FTP access explained in another Howto by Zope member nemeth: http://www.zope.org/Members/nemeth/usingEmacsWithZope --- Alastair

Squishdot with access restrictions
by Ragnar Beer 13 Dec '00

13 Dec '00

Howdy Zopistas! Has anyone installed a Squishdot site with access restrictions? I've got the problem that as soon as I take away the "view" and "access contents information" permission from the anonymous user in my Squishdot site I cannot use the search interface anymore but only get KeyErrors (icon or thread_path depending on which permission I take away). I'm using Squishdot 0.7.2 and Zope 2.2.2. Any help appreciated! Ragnar

Response.redirect problem **sometimes** on netscape
by Didier Georgieff 13 Dec '00

13 Dec '00

Hello, I'm doing a form for deleting objects within our site design (no manage interface). All goes well, with a FORM <FORM ACTION="<dtml-var URL1>" METHOD="POST"> ..... [ we create the ids:list here] <INPUT TYPE="SUBMIT" NAME="myDelete:method" VALUE="Del"> myDelete method does also the redirect on the calling page. <dtml-if ids> <dtml-call "manage_delObjects(ids)"> </dtml-if> <dtml-call "RESPONSE.redirect(URL1)"> In IE5 works fine, but NO REDIRECT on Netscape 4.51 (blank page and the post data still there), while the RESPONSE.redirect **works** on other occasions with N4.51. Is it a known problem, or a problem calling manage_delObjects bfore redirection ? If not, seems like a bug somewhere in the headers ? Thanks in advance. -- Didier Georgieff DDAF du Bas-Rhin - Cellule SIG 2, rue des Mineurs 67070 Strasbourg Cedex tél : 03.88.25.20.33 - fax : 03.88.25.20.01 email : didier.georgieff(a)agriculture.gouv.fr SIT du Bas-Rhin : http://www.bas-rhin.sit.gouv.fr GéoWeb http://sertit10.u-strasbg.fr

turning off inheritance
by Kyler B. Laird 13 Dec '00

13 Dec '00

I am working on generating a directory from Zope objects. There is a folder full of units (other folders). These units contain people (more folders). Units and people both have contact information stored in their properties. How do I detect if a person has, for example, 'contact_email' set? I've tried <dtml-if "_.hasattr(this(), 'contact_email')"> It succeeds if the person doesn't have contact_email set but its unit does. I've also tried variations of <dtml-with ... only>, with no success. Any pointers? Where could I have found the answer to this on my own? Thank you. --kyler

HTTPServer.py patch
by Oleg Broytmann 13 Dec '00

13 Dec '00

Hi! With the recent patch I have problems connecting directly to ZServer (port 8080) - Zope reported error 500 and restarted itself. Connecting through Apache+mod_pcgi2 works. I reverted the patch (restored HTTPServer.py from backup) and can connect to ZServer again. Something wrong with te patch!
